Crosman .177-Cal Steel Breech Kit, Fits 1377, 1740, 1760 & PC77 Air Guns

First off the Website is very well put together and very easy navigate. My item was as advertised and very well packaged. Item also shipped out fast and item delivered on time

Honestly nothing in my opinion

Yes check out there refurbished section to find great deals on used items

Great product Adds Mutch better accuracy to an already accurate pistol_ rifle. easy to install

pay a little more attention to manufacturing as the transfer port didn't line up & had to file off about 1/32 nd of an inch to get it to fit. the barrel was purchased from CROSSMAN directly so there not to blame.

I rolled the barrel with my left hand on my lap while holding a mill file with my right 3 or 4 minutes later it fit nicely. same thing with the loading area inside the barrel; cone shaped Dremel bit works nicely. despite this its still a good product more solid than others I've tried.

everything fits many different air guns finish matched every Crosman air gun I've put them on.

pay a little mor attention to manufacturing tolerances. I had to file 1.6 mm of a Crosman barrel before the transfer port would line up and the bolt would close.

converted a Crosman 362 into a 177 Cal rifle with this one & it upped the velocity to 977 fps with a 7 gr wadcutter just what I wanted. now I'll go to the 10.5 s for accuracy. should bring the fps down to the 800s perfect for some target work (found a 3x9x40 hammers online why doesn't PA sell them their awesome possum scopes

will fit on my Crosman 362 perfectly.

include breach screw washers so the pellet wont catch & mangle the head of the pellet

I'm transforming a 362 into a 177 Cal hoping for awesome speed increase. bought a 177 Cal barrel from Crossman put a washer behind the hammer spring & pump it up 15 times yea it will work without saving any air. (lets call this one a 367 ? rats i should have patented that. next epoxy that transfer port bushing in place you're losing a lot of air right there PS I always file out those transfer ports for max power

Great product works like it should. finish matches up nicely with gun finish.

should come with breach screw washers as standard items. pellets will catch sometimes in that area.

Dennis at baker air sent me breach screw washers free as I buy lots of stuff from him. If the bolt handle is loose turn bolt probe 180 degrees & reinstall handle that will more than likely fix it.these also fit the Crossman 362 pump rifles same platform as the 1322 1377 pistols

It was pretty simple to install and it really changed the character of the gun. Everything feels much tighter and more solid now. Accuracy seems to have improved as well although that could be because of the dovetail sight that this breech can accept.

The bolt handle needed a little filing to properly fit. Not a big deal.

It does add noticable weight

This is far more secure than the plastic breech.

The breech screw - the head of the small breech screw sits in a large counter bore that pellets fall in. This makes them harder to get into the chamber without damaging. (This has not been a problem for me on the .22 version).

Just what I wanted. Excellent quality. Very happy.

The steel breech is more rigid than the plastic one, and has more support surface for the barrel.

The undercut on the breech is contoured 2240/1740 tube. The 1377/1322 tube is slightly smaller in diameter. It still tightens down, but the tolerance is kind of sloppy. I wish they would make one specifically for the 1377/1322

The O-Ring on the bolt probe seems to ship dry. Oil it as detailed in the airgun's owners manual to prolong the life of the seal.

Steel, nice weight and good finish. Secures very nicely and was easy to install after some fiddling even without looking at instructions(do still look at instructions there's no reason not to).

Blue loctite on the bolt handle threads but you can do it yourself quite easy and loctite is always good to have around anyways, it'll just come loose after working the action a few times(or maybe I'm just rough).

This with the stock makes for a very accurate little plinker.
